None of the meals are able to replace a normal meal for me from my experience so far, but as snacks they are delicious. i am getting addicted to the bars, very very good. Shakes are the least fulfilling, little drinks are the most fulfilling. Overall very good and easy to track nutrients and get additional macronutrients but for the protein shakes i think ill use the powder not really for shakes but rather for smoothies or pancakes or different baking stuff so if you could explain how to substitute for example flour with it, it would be super great! also, delivery seems a bit slow
